Application January 13, 1944, Serial No. 518,149

3 Claims.

This invention relates to new and useful improvements in cuttingmachines for shingles, and more particularly to a hand-type device,whereby shingles can be cut at the proper length and width in a quickand convenient manner.

The principal object of the present invention is to .provide such acutteras above stated with an adjustable center point to the end thatwhen a shingle is about to be cut and has been properly marked at theopposite ends thereof, the movable cutter blade of the cutting device islet down gently until the center point rests on the pencil mark at oneend of the shingle, to the end that with this end of the plate securelyheld on the pencil point, the front or opposite end of the shingle maybe swung around until the pencil mark on the other end of the shinglecomes directly under the movable blade, whereupon the shingle can beaccurately cut.

Other objects and advantages of the invention will become apparent tothe reader of the following description.

In the drawing:

Figure 1 is a side elevational view of a conventional machine showingthe present improved centering means.

Figure 2 is an enlarged fragmentary detailed sectional view taken online 2-2 of Figure 1.

Figure 3 is a fragmentary sectional view taken on line 3-3 of Figure 2.

Referring to the drawing, wherein like numerals designate like parts, itmay be seen that numeral 5 for the most part denotes a conventionalshingle cutter, numeral 6 denoting an upper frame pivoted, as at 1, upona lower base frame 8. An actuating frame 9, is link-connected, as at ID,to the base frame 8 and rockably mounted on the frame 6 and caused toforce the upper frame 6 toward the base frame 8. The base frame 8supports a blade II, while the upper frame 6 supports a blade I2 whichis interrupted and divided into apair of sections a, b by the presenceof the present invention which is generally referred to by numeral l3.

As can be seen in Figure 1, the upper blade I2 has a plurality ofadjusting screws I4 and in accommodating the present invention I3, oneof these screws is removed for the purpose of I accommodating acentering pin I5, which is substantially longer than the adjustingscrews I4 and extends downwardly between the adjacent ends of thesections a, b of the blade I2. The lower end of the pin I5 is pointed,as at I6, while its upper end is threaded, as at I1, projecting into theupper frame 6 where it is provided with an adjusting nut I8. The lowerblade II has an interruption or notch I9 therein for receiving the pointI6 of the centeringpin I5 when the blades I I, I2 come together.

It will, of course, be observed that the extreme point of the pointedend N3 of the pin I5 is in a plane with the cutting edge of the blade I2and also the blade II. This centering pin I5 will in no way interferewith the cutting action of the blades I I, I2, but will permit swivelingof the shingle to the end that accurate cuts can be made throughasbestos and other materials forming shingles with but a minimum amountof care and effort.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed I as'new is:

1. A shingle cutting device comprising a lower fixed blade, an uppermovable blade, a centering pin extending downwardly from the upperblade, and a hand device for actuating the movable blade, said bladesand pin being in a common plane. 7

2. A shingle cutting device comprising a lower fixed blade, an uppermovable blade, a centering pin extending downwardly from the upperblade, and a hand device for actuating the movable blade, said upperblade being interrupted to accommodate the plum the plane thereof.

3. A shingle cutting device comprising a lower fixed blade, an uppermovable blade in the plane of the fixed blade, a centering pin extendingdownwardly from the upper blade in the plane of said blades, and a handdevice for actuating the movable blade, the lower blade being formedwith a recess for accommodating said pin when the blades are broughttogether.
